Products

Compact Raman spectrometers and integrated Raman systems

Modular to fully integrated Raman spectrometer systems optimized for field, lab, and OEM use, covering excitation wavelengths from deep-UV to 1064 nm and offering matched probes and laser integration options.

Preconfigured and OEM OCT spectrometer modules

Drop-in spectral-domain OCT spectrometers in multiple optomechanical series optimized for research, OEM integration, or long-range imaging. Options cover tradeoffs in bandwidth, axial resolution, and imaging depth (including ultra-fine spectral-resolution configurations enabling extended imaging depth up to ~12 mm at ~800 nm) and support high-speed acquisition via USB 3.0 or Camera Link interfaces.

Matched Raman probes and fiber-optic accessories

Sampling probes and fiber-coupled accessories designed to match spectrometer numerical aperture and sampling requirements (short focal length, immersion probes, laboratory lengths).

Custom and large-format diffractive optics for astronomy

Supply of VPH gratings and grism elements designed for astronomical spectrographs across UV–NIR with dispersion and mechanical sizing suitable for major telescopes, and participation in instrument-level testing and deployment.

HD 1800 l/mm grating

A high-density multiplexed transmission grating designed to change how Raman and OCT spectrometers are designed by providing broader bandwidth efficiency.

Grating: 800 l/mm @ 1030 nm CWL

VPH transmission grating for pulse compression and NIR applications at 1030 nm.
